Selected FAQ

Q:
Nothing is projected on the screen. What should I do?
A:
Try the following:

  • Make sure the lens cover is open or off.


  • Press the A/V Mute button to see if the image was temporarily turned off.


  • Press the projector’s Power button to wake it from standby or sleep mode. Also see if your connected computer is in sleep mode or displaying a blank screen saver.


  • If you unplugged the projector and plugged it right back in, press the Power button to turn on the projector (with Direct Power On enabled.)


  • Check the settings on the Signal menu to make sure they are correct for the current video source.


  • Adjust the Brightness setting or select the Normal Power Consumption setting.


  • Check the Display setting to make sure Messages is set to On.


  • If the projector does not respond when you press the control panel buttons, the buttons may be locked. Unlock the buttons.


  • If the projector does not respond when you press buttons on the remote control, make sure the remote receivers are turned on.


  • If you’ve connected a laptop computer, make sure it’s set to display on an external monitor.


  • If you’re using a PC notebook:

    • Press the function key that lets you display on an external monitor. It’s often labeled with an icon such as , but it may also be labeled CRT/LCD. You may have to hold down the Fn key while pressing it. Check your laptop’s manual or online help.

      On most systems, the key lets you toggle between the LCD screen and the projector, or display on both at the same time. Allow a few seconds for the projector to sync up after pressing it.

      If that doesn’t work, press the ? Help button on the projector for a list of laptop brand-specific button combinations you can press to switch to an external display.


    • If the function key doesn’t let you display simultaneously on both screens, you might need to use the Display utility in the Windows Control Panel to make sure that both the LCD screen and external monitor port are enabled. From the Windows Control Panel, open the Display utility. Click the Settings tab, then click Advanced. The method for adjusting the setting varies from computer to computer; you may need to click a Monitor tab, then make sure the external Monitor port is set as your primary display or enabled. See your computer manual or online help for details.


    If you’re using Macintosh OS X:

    1. Make sure the projector is connected to your Macintosh.


    2. Select System Preferences from the Apple menu and click Displays.


    3. Click Detect Displays.


    4. To display the entire desktop on both your projector screen and LCD screen, click the Arrangement or Arrange tab. (If you don’t see this tab, make sure it isn’t hidden by another window.)


    5. Click Mirror Displays in the lower corner of the screen. One of the monitor icons automatically moves on top of the other.
